LongCat-Next: Turning Images, Audio, and Text into Tokens – What’s Next?

LongCat-Next is a 68.5‑billion‑parameter discrete‑native autoregressive multimodal model that tokenizes images, audio and text, challenges the belief that visual tokenization loses detail, matches specialized models on fine‑grained tasks, and demonstrates that joint understanding‑generation training can even improve generation quality.

Meituan’s Fully Discrete Multimodal Base (LongCat-Next) Shows All Physical Signals Can Converge to Tokens

LongCat-Next, a 3‑billion‑parameter multimodal model released by Meituan, adopts a pure discrete token‑based architecture (DiNA) and next‑token prediction, outperforming same‑size rivals on OmniDocBench‑EN, CharXivRQ, and matching QwenVL on visual tasks, while avoiding catastrophic forgetting and achieving a SWE‑Bench score of 43.0, as demonstrated through extensive benchmarks, receipt extraction, OCR, audio dialect reasoning, and image generation experiments.
